UNITED sT-Ares LIQUID vCOOLER George W. Williams,

The Creamery oak Park, 111'assignor to Package Mfg. Company, Chicago, Ill., a corporation of Illinois Original No. 1,821,489, dated September 1, 1931, Serial No. 512,013, January 29, 1931. Application for reissue June 10, 1932. Serial No.

6 Claims. (Cl. 257-183) The invention relates to liquid coolers, and more particularly to the type in which a series of vertically arranged horizontal tubes contain a coollingfmedium while the liquid being cooled iiows by gravity over their outer surfaces.

In coolers of this type. it has been found that condensation of moisture from-the atmosphere forms upon the extreme ends of the tubes Where the liquid being cooled normally does not flow,

and also upon the headers or standards in which the tubes are supported, such condensation following the tubes and becoming intermingled with the liquid being cooled. In the case of milk coolers such an occurrence is obviously objectionable, and in the past it has been attempted to avoid it by aiiixing a single ring about each end of each tube spaced from the adjacent header, the rings being inclined from vertical so that the lower side of each ring is positioned inwardly of the upper side of the next lower ring.

The single rings divert the marginal flow of milk or other liquid inwardly away from the tube extremities and headers, but nevertheless are decient in that the condensation forming outwardly of the rings follows the tubes to the rings, then downwardly along the outward faces of the rings to the underside, from whence the condensation drips inwardly of the next lower rings and is there intermingled with the milk.

It is the object of the present invention to provide a construction in coolers of this type which accomplishes lboth the inward diversion of the milk and the outward diversion of the condensation, and thus prevents any contamination of the milk by the intermingling therewith of the condensation.

Other objects and advantages will be apparent in the following detailed description of a preferred embodiment of the invention illustrated in the accompanying drawing.

In the drawing, Fig. 1 is a fractional view in elevation of a cooler showing portions of the tubes and their supports. Fig. 2 is a cross sectional view in elevation taken on the plane of the line 2 2 in Fig. 1.

Referring to the drawing, a series of horizontal tubes 1 are arranged in vertical spaced relation, and supported in a standard 2. The tubes are endwardly connected, as by return headers 3,

for continuous serial flow of a heatexchange medium within the tubes. Mounted above the uppermost tube is a distribution pipe 4 from which milk, or other liquid to be cooled, is discharged through a series of openings 5 and distributed over the top tube. The milk'flows by gravity down over the several succeeding lower tubes, is thereby cooled, and is collected in a pan or trough (not shown) positioned below the lowermost tube. l

Mounted on the respective end portions of each tube 1, adjacent to but spaced from the standard 2, is a baie or diverting device 6.l The ylatter preferably comprises a pair of rings, joined at their upper edges and substantially separated at their lower edges, the joined portions of each pair of rings being positioned directlybelow the separated portions of the pair of rings mounted on the tube next above. The rings are aixed to the tubes by solder or other suitable means. The outer'peripheries of the rings may be square or any other suitable form, and they may be constructed of one piece with the lower portion split vertically for divergent formation `in two later- 'ally inclined wings.

It will here be apparent that as the milk or other liquid under treatment flows down over the tubes, the lateral edge of the stream is diverted inwardly by the inner portion of the respective rings, and falls upon the next lower tube inside of the ring on the lower tube. Likewise,the condensation accumulated on the tube ends out-` wardly of the rings ows down the outer inclined portion of the respective rings and drips therefrom outwardly of the next lower ring. Thus, intermingling of milk and condensation is positively prevented. I l

I claim as my invention:

1. In a cooler having a series of tubes arranged ln vertically spaced relation and adapted for the flow thereover of liquid, the combination therewith of flow diverting members mounted one above `another about the respective tubes, said members having narrow upper edges and downwardly divergent lateral surfaces whereby liquid owing downwardly over the surfaces of said tubes at either side of said members is prevented from passing to the other side of said members.

2. In a cooler having a series of vertically spaced tubes for the ow of liquid thereover, a split ring mounted upon each of said tubes, said ring having a joined lupper portion and a divergently separated'lower portion, said rings being positioned with the joined upper portion of each directly below and between the separated lower portions of thenext higher ring.

3. In a cooler having a horizontally positioned tube for the flow of liquid thereover, a diverting member mounted upon and encircling Asaid tube, said member comprising a pair of rings having `so y their upper edges joined and their lower edges substantially separated.

4. In a cooler having a plurality of vertically spaced horizontal tubes, a plurality ofV rings en- .circling said tubes respectively and arranged ini vertical serial relation, said rings having unitary upper portions and divided spaced lower'por' tions whereby the lateral surfaces of the divided lower portions laterally overextend the unitary" upper portions of the next lower rings.

5. A cooler comprising a vertical series of. horizontally disposed cooling'tubes provided .near each of their outer ends with inwardly and outwardly inclined guard anges which are integral with said tubes. y p

6. A cooler comprisinga vertical series of horizontally disposed l cooling tubes provided near their outer ends with inwardlyfand outwardly inclined guard flanges, said outwardly inclined flanges being joined to and extending from the said inwardly inclined flanges.
